API Development
Robust, documented APIs that your ecosystem depends on.
APIs are the connective tissue of modern software. We design and build REST and GraphQL APIs that are performant, well-documented, versioned, and built to handle the abuse that production traffic invariably brings — whether you are exposing your platform to third-party developers or integrating your internal services.

Deliverables
What We Deliver
API Design Document
A complete OpenAPI 3.0 or GraphQL schema specification agreed with stakeholders before implementation begins — no surprises.
Production API
A fully implemented, tested, and deployed API with authentication, rate limiting, error handling, and request validation.
Developer Documentation
Interactive API docs (Swagger UI or GraphQL Playground), getting-started guides, and code examples in multiple languages.
SDK / Client Libraries
Auto-generated or hand-crafted client SDKs for JavaScript, Python, and other key languages used by your consumers.
API Gateway & Security Layer
Rate limiting, API key management, JWT/OAuth2 authentication, and request logging via AWS API Gateway, Kong, or Apigee.
Methodology
How We Work
API Design Sprint
We run a collaborative design session to define resource models, endpoint contracts, authentication patterns, and versioning strategy. Output: a signed-off OpenAPI spec.
Mock & Validate
We deploy a mock server from the spec so consumer teams can begin integration work in parallel, reducing total project timeline.
Implementation & Testing
Backend engineers implement the API with comprehensive test coverage including contract tests that guarantee the spec is honoured.
Security Audit & Launch
Pre-launch security review covering auth bypass, injection vulnerabilities, and rate limit testing before the API is opened to consumers.
